The chair is plush and upholstered in a rich velvet fabric, contrasting with the soft, ambient lighting. The novel’s cover features intricate, gothic-inspired artwork, adding a mysterious ambiance. The image is rendered in high definition, emphasizing the textures of the chair’s upholstery, the pages of the book, and the subtle play of light and shadow in the room, creating an atmosphere of tranquility and introspection. The gentle hum of a distant appliance adds a sense of normalcy to the scene, grounding the moment in everyday life. The room, bathed in soft natural light, seems to invite contemplation, making it an ideal space for deep thought and reflection. The air is still, carrying a faint scent of fresh laundry, which adds a comforting touch to the ambiance. Overall, the setting is conducive to a peaceful state of mind, where one can escape the hustle and bustle of the outside world and find solace in the simplicity of the moment.

接下来,我们利用题目给出的条件 \(a_5 = 3a_3 + 4a_1\),可以写成:
\[ a_1 q^4 = 3a_1 q^2 + 4a_1 \] \[ q^4 = 3q^2 + 4 \quad \text{(2)} \]

现在我们解方程 (2):
\[ q^4 – 3q^2 – 4 = 0 \] 设 \(x = q^2\),则方程变为:
\[ x^2 – 3x – 4 = 0 \] 解这个二次方程:
\[ x = \frac{3 \pm \sqrt{9 + 16}}{2} = \frac{3 \pm 5}{2} \] \[ x = 4 \quad \text{或} \quad x = -1 \]

由于 \(x = q^2\),且 \(q^2\) 必须为正数,所以 \(x = 4\),即:
\[ q^2 = 4 \] \[ q = 2 \quad \text{或} \quad q = -2 \]

接下来,我们分别代入 \(q = 2\) 和 \(q = -2\) 到方程 (1) 中验证:

1. 当 \(q = 2\) 时:
\[ a_1 (1 + 2 + 4 + 8) = 15 \] \[ a_1 \cdot 15 = 15 \] \[ a_1 = 1 \]

2. 当 \(q = -2\) 时:
\[ a_1 (1 – 2 + 4 – 8) = 15 \] \[ a_1 \cdot (-5) = 15 \] \[ a_1 = -3 \]

由于 \(a_1\) 必须为正数,所以 \(q = -2\) 不成立。

综上所述,正确答案是 \(q = 2\),\(a_1 = 1\)。

再回到题目中的选项,正确答案是 \(D\),即“所有上述气体”。

所以,用户回答的答案 \(B\) 是错误的。

因此,答案是:
